LED & UV Liquid Light Guides for Spot Lamps

For efficient, high-intensity spot lamp curing, liquid light guides are the most economical means for delivering light to cure adhesives and coatings. These curing wands transmit UV and LED energy from a source mounted inside of a spot-curing system to the targeted curing area. Light Guides help minimize degradation of light intensity over time and transmit the highest light intensity available for UV and LED curing. 

Some of the important factors to consider when choosing a UV curing wand are:

• Length – Available in multiple lengths; one meter is most common 
• Diameter – Inside diameters available in 3 mm, 5 mm, or 8 mm.  Although the 5 mm guide will register a higher intensity, the 8 mm version provides more curing power (intensity x area) because the opening captures more of the light emitted from the curing system bulb. Each pole of a multipole UV wand has an inside diameter of 3 mm.
• Number of Poles – Available in one to four-pole configurations for curing multiple points simultaneously. Light-emitting from a spot lamp can be channeled through a single-pole or split between multiple poles. Each pole of a multipole light guide emits equal intensity (typically ±10% for liquid-filled) and all share a common shutter.
• Connection Type – There are two types of connectors used in the spot curing lamp industry; “Wolf” and “D” connectors. Both connectors are available in Dymax liquid light guides. “D” connectors are an industry standard and compatible with current Dymax lamp designs. “Wolf” connectors are primarily found in older curing systems.
• Curing Area/Intensity vs. Distance – The UV/LED light emitted from a Light Guide diverges. As a result, intensity decreases, and the curing area increases with distance from the end of the light guide.
